AI Technical Summary
The fixed sensitivity of existing leakage current protection devices limits their application scenarios and makes them unable to meet the needs of scenarios with different safety requirements.
A leakage current protection device was designed, including a detection circuit, a comparison circuit, a threshold adjustment module, and a control circuit. By forming a leakage current detection loop, the device outputs a detection signal for comparison, and controls the circuit breaker to disconnect the power grid when the detection signal is greater than a set threshold. At the same time, the sensitivity is adjusted by simulating leakage current resistance to adapt to different application scenarios.
The sensitivity of the leakage current protection device can be adjusted to meet the needs of different application scenarios and improve safety, especially providing better protection in scenarios with high safety requirements such as hospitals, swimming pools and mines.
